There are a few ways of doing this, but I'll use the one involving finding the slope of the line and then using it in point slope form.

Say m represents slope.

m = $(6 - 12) / (19 - - 17)$

m = $-6/36$

m = $- 1/6$
The slope is $-1/6$

y - y1 = m(x - x1)

Select your point, say (19, 6), and plug it into the formula shown above.

y - 6 = $-1/6$ (x - 19)

y - 6 = $-1/6x$ + $19/6$

y = $-1/6x$ + $55/6$

The equation of your line is y = $-1/6x$ + $55/6$

What is the equation of the line between (-17,12)(-17,12) and (19,6)(19,6)?
